Answer to Question 1

Ans:
A

Feedback:

Oral tests now exist for preliminary diagnosis of HIV. Medications for AIDS do not cure the disease, and incidence is increasing among heterosexuals. Condoms provide effective protection from the virus.

Answer to Question 2

Ans:
B

Feedback:

Serum sickness is characterized by the deposition of antigen-antibody complexes in blood vessels, joints, heart, and kidney tissue. The deposited complexes activate complement, increase vascular permeability, and recruit phagocytic cells, all of which can promote focal tissue damage and edema. Serum sickness is not synonymous with an Arthus reaction. Antibody binding to specific target cell receptors causing a change in cell function is characteristic of antibody-mediated cellular dysfunction. Serum sickness is not associated with the activation of the complement system.
